Liquid crystal display device

Abstract

An LCD device is disclosed, in which a lamp housing is formed of a reflecting sheet instead of a metal material, to obtain the simplified manufacturing process and to decrease the manufacturing cost. The LCD device includes an LCD panel; a light-guiding plate below the LCD panel; a lamp at one side of the light-guiding plate; a first reflecting sheet below the lamp and the light-guiding plate; a support main corresponding to an outer side of the LCD panel to support the lamp, the first reflecting sheet and the LCD panel; a second reflecting sheet between the lamp and the support main; a case top covering the outer side of the LCD panel and the support main; and a cover bottom below the reflecting sheet to be coupled with the case top.

1 . A liquid crystal display (LCD) device comprising: 
 an LCD panel;    a light-guiding plate below the LCD panel;    a lamp at one side of the light-guiding plate;    a first reflecting sheet below the lamp and the light-guiding plate;    a support main corresponding to an outer side of the LCD panel to support the lamp, the first reflecting sheet and the LCD panel;    a second reflecting sheet between the lamp and the support main;    a case top covering the outer side of the LCD panel and the support main; and    a cover bottom below the first and second reflecting sheets to be coupled with the case top.    
     
     
         2 . The LCD device of  claim 1 , wherein the second reflecting sheet is formed on an inner surface of the support main adjacent to the lamp.  
     
     
         3 . The LCD device of  claim 1 , wherein an inner surface of the support main is formed in a shape of ‘ ’, and the second reflecting sheet adheres to the inner surface of the support main.  
     
     
         4 . The LCD device of  claim 1 , wherein the second reflecting sheet is formed of the same material as the first reflecting sheet.  
     
     
         5 . The LCD device of  claim 1 , further comprising diffusion, prism and protection sheets between the light-guiding plate and the LCD panel.  
     
     
         6 . The LCD device of  claim 1 , wherein a lower substrate of the LCD panel has a margin as compared with an upper substrate of the LCD panel.  
     
     
         7 . The LCD device of  claim 1 , wherein the support main and the lamp correspond to non-pixel regions of the LCD panel.  
     
     
         8 . The LCD device of  claim 1 , wherein the second reflecting sheet adheres to the inner surface of the support main by an adhesive.  
     
     
         9 . A liquid crystal display (LCD) device comprising: 
 an LCD panel having an outer side;    a light guiding plate disposed below the LCD panel;    a lamp adjacent the light guiding plate;    a first reflecting sheet disposed below the lamp and the light guiding plate;    a support main corresponding to the outer side of the LCD panel, the support main supporting the lamp, the first reflecting sheet and the LCD panel;    a lamp housing surrounding the lamp where the lamp housing is a second reflecting sheet;    a case top which covers the outer side of the LCD panel and the support main; and    a cover bottom below the first and second reflecting sheets, the cover bottom coupling with the case top.    
     
     
         10 . The LCD device of  claim 9 , wherein the second reflecting sheet is formed in an inner surface of the support main such that the second reflecting sheet is adjacent the lamp.  
     
     
         11 . The LCD device of  claim 9 ,. wherein the support main further comprises: 
 a first section; and    a second section where the first section and the second section are formed at right angles to one another wherein the second reflecting sheet adheres to both the first section and the second section with an adhesive.    
     
     
         12 . The LCD device of  claim 9 , wherein the first reflecting sheet and the second reflecting sheet are formed from a same material.  
     
     
         13 . The LCD device of  claim 9 , wherein the LCD panel further comprises: 
 an upper substrate; and    a lower substrate where the lower substrate includes a margin.    
     
     
         14 . The LCD device of  claim 9 , wherein the support main and the lamp correspond to non-pixel regions of the LCD panel.
